Stainless Steel Surface Finishing Options
Explore a wide range of stainless steel surface finishes tailored for both functional performance and visual enhancement. From bead blasting to black oxide coating, each process enhances corrosion resistance, aesthetics, and part durability—choose the right finish for your application.
Brushing
Creates fine, directional textures using abrasive belts or brushes to achieve a matte, decorative finish with a consistent grain pattern.
Sandblasting
High-speed abrasive particles are blasted onto the surface to remove oxide layers and residues, increase roughness, and enhance adhesion for subsequent coatings.
Powder Coating
A dry powder is electrostatically sprayed onto the surface and then cured at high temperature, forming a durable, weather-resistant finish available in a variety of colors.
Passivation
Chemical treatment to enhance the corrosion resistance of metals by removing free iron from the surface.
Polishing
Polishing removes surface flaws and creates a reflective, smooth finish. It’s used to improve aesthetics, reduce friction, and prepare parts for secondary coatings.
Plating
Black Oxide
